These types of numbers are usually behind an Interactive Voice Response (IVR) system, which a WhatsApp registration call cannot navigate. Instead, WhatsApp is able to share with you 1 to 2 phone numbers that the registration phone call will come from. You can use this information to create an allowed list for those numbers so that you can redirect the registration call to an employee or mailbox where the registration code will be captured.
